I’ve done an overly simple CPU benchmark test against Azure, AWS and Oracle cloud instances to get a rough idea how they perform in comparison. I’ve used sysbench for this (details below), which basically spits out you the time it needs to find prime numbers.

The numbers

The green rows are setups that you would actually use – you would not select a server instance with just one or two cores if the Oracle database processor license allows you to use it for a server with more cores.

Results

One Oracle database SE2 processor license on Azure will get you only 22% of the CPU power compared to what you get in the Oracle cloud. With AWS you get around 40% of the CPU power compared to the Oracle cloud.
